A colourless inorganic salt (A) decomposes completely at about 250^@ C to give only two products (B) and ( C) , leaving no residue. The oxide ( C) is a liquid at room temperature and neutral to litmus paper while the gas (B) is a neutral oxide. White phosphorous burns in excess of (B) to produce a strong white dehydrating agent. Write balanced equations for the reactions involved in this process.

A colourless inorganic salt (A) decomposes completely at about 25^(@)C to give only two products, (B) and (C ), leaving no residue. The product (C ) is a liquid at room temperature and neutral to moist litmus paper while the gas (B) is a neutral oxide. White phosphorus burns in excess of (B) to produce a strong white dehydrating agent. Write balanced equations for the reactions involved in the above process.

A colourless inorganic compound (P) decomposes on heating to give two products (Q) and (R). (Q) is a colourless neutral gas with a sweet odour which when burnt with phosphorous produces a strong dehydrating agent (S) while (R) is a neutral liquid at room temperature. Identify P, Q, Rand S.
